Currently, Indian supercomputers are at a teraflop stage. This means they can perform several trillion floating point operations per second. China, Japan and the U.S. have already achieved petaflop capability. Such supercomputers are able to perform a thousand trillion floating point operations per second.

These countries have also begun work on the next level - exascale - to develop machines with the capacity of an exaflop or one million teraflops.
In order to remain in the race, India would first need to develop a petaflop machine and then aim for exascale. When contacted, Dr T. Ramasami, secretary, department of science and technology, confirmed the development, revealing that the programme had been conceived with a view 'to position India strongly in supercomputing' and would be implemented in mission mode.
